Have you ever written a famous person a letter and not gotten a response? Yeah, me neither – who has the time, really? But I always find it interesting what kind of people actually response.

A young man named Adam wrote a letter to Pete Docter, director of Pixar’s Monsters Inc and Up, in 2008 asking for a signed photo. He didn’t get a signed photo, but a few months later he did get a response — not just some form letter, but a handwritten two-sided letter, complete with personal doodles from Docter. How cool is that? Check out the full letter, after the jump.
